| palatine tonsil | Palatine tonsils are the tonsils that can be seen on the left and right sides at the back of the throat [Brenda]. | — |
| tongue | A fleshy movable process of the floor of the mouths of most vertebrates that bears sensory end organs and small glands and functions especially in taking and swallowing food and in humans as a speech organ [Brenda]. | — |
| salivary gland | The glands of the oral cavity whose combined secretion constitutes the saliva [Brenda]. | — |
| tooth | 1: One of the hard bony appendages that are borne on the jaws or in many of the lower vertebrates on other bones in the walls of the mouth or pharynx and serve especially for the prehension and mastication of food and as weapons of offense and defense.n2: Any of various usually hard and sharp processes especially about the mouth of an invertebrate [Brenda]. | — |
| nasopharynx | The upper part of the throat behind the nose. An opening on each side of the nasopharynx leads into the ear [Brenda]. | — |
| oropharynx | The Oropharynx (oral part of the pharynx) reaches from the Uvula to the level of the hyoid bone [Wikipedia: http://en.wikipedia.org/wiki/Oropharynx]. | — |
| hypopharynx | The portion of the pharynx that lies below the upper edge of the epiglottis and opens into the larynx and esophagus [Brenda]. | — |
| gastric mucosa | The mucous coat of the stomach [Brenda]. | — |
| small intestine | The part of the intestine that lies between the stomach and colon, consists of duodenum, jejunum, and ileum, secretes digestive enzymes, and is the chief site of the absorption of digested nutrients. The proximal portion of the intestine [Brenda]. | — |
| vermiform appendix | A narrow blind tube usually about three or four inches (7.6 to 10.2 centimeters) long that extends from the cecum in the lower right-hand part of the abdomen, has much lymphoid wall tissue, normally communicates with the cavity of the cecum, and represents an atrophied terminal part of the cecum [Brenda]. | — |
| large intestine | The more terminal division of the vertebrate intestine that is wider and shorter than the small intestine, typically divided into cecum, colon, and rectum, and concerned especially with the resorption of water and the formation of feces [Brenda]. | — |
| greater omentum | The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and reflects on itself to ascend to the transverse colon before reaching to the posterior abdominal wall. The common anatomical term "epiploic" derives from "epiploon" from the Greek "epipleein" meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines [Wikipedia: http://en.wikipedia.org/wiki/Greater_omentum]. | — |
| lesser omentum | The lesser omentum (small omentum; gastrohepatic omentum; omentum minus) is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach and the start of the duodenum [Wikipedia: http://en.wikipedia.org/wiki/Lesser_omentum]. | — |
| liver | 1: A large very vascular glandular organ of vertebrates that secretes bile and causes important changes in many of the substances contained in the blood (as by converting sugars into glycogen which it stores up until required and by forming urea).n2: Any of various large compound glands associated with the digestive tract of invertebrate animals and probably concerned with the secretion of digestive enzymes [Brenda]. | — |
| spinal cord | The cord of nervous tissue that extends from the brain lengthwise along the back in the vertebral canal, gives off the pairs of spinal nerves, carries impulses to and from the brain, and serves as a center for initiating and coordinating many reflex acts [Brenda]. | — |
| gall bladder | A small, pear-shaped muscular sac, located under the right lobe of the liver, in which bile secreted by the liver is stored until needed by the body for digestion [Brenda]. | — |
| bile duct | Any of the ducts that convey bile in and from the liver [Brenda]. | — |
| exocrine pancreas | That part of the pancreas that acts as an exocrine gland, consisting of the pancreatic acini, which produce pancreatic juice and secrete it into the duodenum to aid in protein digestion [Brenda]. | — |
| kidney | 1: One of a pair of vertebrate organs situated in the body cavity near the spinal column that excrete waste products of metabolism, in humans are bean-shaped organs about 4 1/2 inches (11 1/2 centimeters) long lying behind the peritoneum in a mass of fatty tissue, and consist chiefly of nephrons by which urine is secreted, collected, and discharged into a main cavity whence it is conveyed by the ureter to the bladder.n2: Any of various excretory organs of invertebrate animals [Brenda]. | — |
| ureter | The tube that carries urine from the kidney to the bladder [Brenda]. | — |
| bladder | A membranous sac in animals that serves as the receptacle of a liquid or contains gas [Brenda]. | — |
| urethra | The tube through which urine leaves the body. It empties urine from the bladder [Brenda]. | — |
| visual apparatus | The visual apparatus consists of nervous tissues immediately concerned in giving rise to sensations, supported, protected, and nourished by other parts. Its essential parts are, (1) the retina, a thin membrane lying in the eyeball and containing microscopic elements which are so acted upon by light as to stimulate (2) the optic nerve; this nerve ends (3) in a part of the brain (visual centre) which when stimulated arouses in our consciousness a feeling or sensation of sight. The visual centre may be excited in very many ways, and quite independently of the optic nerve or the retina; as is frequently seen in delirious persons, in whom inflammation or congestion of the brain excites directly the visual centre and gives rise to visual hallucinations [Newell Martin, 1895: http://bookdome.com/health/anatomy/Human-Body/The-Human-Visual-Apparatus.html]. | — |

| female reproductive system | The internal and external reproductive organs in the female [Brenda]. | — |
